Let's see how much it would cost for 8 batteries by each package

1) 3.92 x 2 = 7.84

2) 7.60

the second package as it would be much cheaper

A: no solution!

first, simplify each side of the equation.

3x + 5 - 10x simplifies to -7x + 5.
8 - 7x - 12 simplifies to -7x - 4.

then, add +7x on both sides of the equation to get the variable alone. if you add 7x to each side, you get left with 0.

so, that leaves 5 = -4 which is not true. so, that means there is no solution.

Check out if I'm right<br> Plz explain..if u have a different answer
Ronch [10]

Answer:

A C

Step-by-step explanation:

A

A is true.The numerator does have 3 terms. The constant term (the 3 at the end) is still a term and counts as a term.

B

A constant term does not count as a coefficient so b is not right, just as you have indicated by not underlining it.

C

C is true. In fact, 2 is the leading coefficent of the denominator.

D

Either A is true or D is, but I don't think they both are. You need a modifier to claim that D is true. If the statement said the numerator has <em>at least </em>2 terms then both A and D would be true. Without the at least, you have to pick one and the one I choose is A

E

This is the tough one. Very sticky. You would think it is true, but it isn't. A constant term is not a coefficient. Coefficients only count when they are with "x"s.
